Abstract

The application discloses a protection method and device for virtualization software. The method includes the following steps: a function of a first attribute which requires to be protected in an original installation package of protected software is converted into a function of a second attribute; a virtualization command conversion engine is utilized, at least a part of a first byte code of thefunction of the first attribute is converted into a second byte code in a user-defined format; a new installation package used for executing on the virtual machine of the protected software is generated according to the function of the second attribute, the second byte code and a user-defined virtual machine explainer; and the user-defined virtual machine explainer is used for reading the second byte code while executing the new installation package and for performing interpretation execution on meaning of the second byte code. According to a scheme, and the safety of the protected software can be effectively guaranteed.

Description

technical field [0001] The present disclosure generally relates to the field of computer technology, and in particular to a virtualization software protection method and device. Background technique [0002] Java (Java) language is used for development on the Android (Android) platform. The Java language is a cross-platform, interpretive language. The source code of Java is compiled into an intermediate code in the form of "byte code". The section code retains a lot of source code information, such as method names, variable names, etc., so that decompilation of java bytecode becomes very easy. In order to protect the application copyright of the Android program, etc., the application program needs to be protected. [0003] Traditional software code protection technologies on the Android platform mainly include code obfuscation and software packing. [0004] Code obfuscation is the act of converting a program's code into a functionally equivalent, but difficult to read and ...
